[issue#306] Add missing ClusterRoles

The cluster-monitoring-operator is required for STF to install. It
creates the required alertmanager-main and prometheus-k8s.
ClusterRoles, and STF relies on these being present.
These are not present when using CRC, so ClusterRoles need to be
explicitly created.

The names of the ClusterRoles have been updated, in case there is some
conflict when cluster-monitoring-operator is installed after STF.

This is a workaround for not having cluster-monitoring-operator
installed: #306

resolves #306
